[Intra-mandibular salivary tumors. Apropos of 3 cases of malignant tumor].

Three cases of intra-mandibular salivary tumors are presented. Two patients died (one with local recurrence, the other with metastasis). 69 cases have been reported in the literature. The lesions present as a progressive swelling of the mandible, with a frequent nervous involvement. The histologic diagnosis is difficult. Mucoepidermoid tumors are the more frequent (71%) but all salivary tumors can be found. An aggressive clinical behavior with local recurrences and/or metastasis (more than 30%) justify a radical treatment.
